Analysis
NAICS 335999 is the 2022 national industry for all other miscellaneous electrical equipment and component manufacturing, part of 33599 (All Other Electrical Equipment and Component Manufacturing). Census lists 40 example activities under it in the official index.
County Business Patterns counts 828 US establishments in this code in 2023, employing 40,468 people at an average annual payroll of $102,050 per employee (85th percentile of national industries). 38% of the establishments have fewer than five employees, which is close to the national mix.
By establishments it ranks 1st of the 2 codes at this level within All Other Electrical Equipment and Component Manufacturing, with 82.2% of them.
Census lists 10 related activities that belong elsewhere, most often in 33513, 3352, 33531 and 335910. Businesses that do several things are classified by their primary activity, the one that generates the most value, so check those boundaries before settling on this code.
Its index entries, the activities Census uses to assign businesses to this code, include amplifiers, magnetic, pulse, and maser, manufacturing, appliance cords made from purchased insulated wire, atom smashers (i.e., particle accelerators) manufacturing and battery chargers, solid-state, manufacturing, among 40 in all.
Its goods appear in 46 statistical lines of the US tariff schedule, mostly under headings 8543 (electrical machines and apparatus, having individual…), 8504 (electrical transformers, static converters (for example…) and 8505 (electromagnets; permanent magnets and articles intended to…). That link is how import data is matched to domestic producers, for example in trade-remedy cases.
Official definition
This U.S. industry comprises establishments primarily engaged in manufacturing industrial and commercial electric apparatus and other equipment (except lighting equipment, household appliances, transformers, motors, generators, switchgear, relays, industrial controls, batteries, communication and energy wire and cable, wiring devices, and carbon and graphite products). Examples of products made by these establishments are power converters (i.e., AC to DC and DC to AC), power supplies, surge suppressors, and similar equipment for industrial-type and consumer-type equipment.
Illustrative Examples:
